The present invention relates to a method for processing transaction details in an electronic cash register, and more particularly, to a method for automatically processing a transaction content in which a transaction is made in units of time.

An electronic cash register is a sales manager that has a function of processing transactions and issuing a receipt for the transactions as is well known. The cash register as described above has a plurality of item keys, numeric keys, and a plurality of keys that can process incoming and outgoing money on the key panel, and inputs the transaction details using these keys and receives the received transaction details. Has been.

However, the conventional cash register is very difficult to issue a receipt for the transaction is made by the time unit by processing the transaction content using only a plurality of item keys and numeric keys. For example, it was very inconvenient to use a cash register to issue a receipt for a transaction at a place such as a parking lot, a billiard room, or a ping-pong room, which has distances in time units. Looking at the process of processing the transaction content with a conventional cash register in the business place as described above, as follows.

When the transaction starts, the person who issues the transaction starts separately, and then calculates the amount per unit time by calculating the transaction time and the transaction end time, which were written by hand at the end of the transaction, and receiving the receipt for the calculated amount. Has been issued using a cash register. Therefore, when the transaction time is recorded incorrectly or miscalculation occurs, there has been a problem that causes friction with the trader, and there is a problem in management.

It is an object of the present invention to provide a method for automatically processing transaction contents in a time unit such that transaction details and amounts are automatically processed by a simple key operation and a receipt can be issued at a place where transactions are made in units of time.

Another object of the present invention is to provide a method of setting and inputting unit time and amount of money per unit time for each transaction type in an electronic cash register.

Still another object of the present invention is to provide a transaction content processing method for automatically processing time-based transaction contents on the basis of a set unit time and an amount per unit time in an electronic cash register.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a hardware block diagram of an electronic cash register, which includes a key input unit 14 for generating key data and an operation command for sales information, a CPU 12 for controlling the overall operation of the cash register, a system operation program and the present invention. A ROM 16 storing a program of the invention, a RAM 18 temporarily storing data, a display unit 20 displaying sales information under the control of the CPU 12, and the CPU 12 A real time clock (RTC) 24 for outputting current time information, and a printing unit 22 for generating a receipt for sales information under the control of the CPU 12.

The electronic cash register as shown in FIG. 1 has a function such as a program mode, a settlement mode, a check mode, a registration mode, a stop mode, and the like according to a switch of a mode switch such as a conventional cash register. Clock keys are provided.

2 is a memory map according to the present invention, in which a transaction item and transaction time storage area A for a corresponding customer and an area B for storing a unit time and an amount per unit time for a transaction item are set.

3 is a flowchart illustrating a method of setting a unit time and an amount per unit time for each transaction type according to the present invention. At this time, the setting in FIG. 3 is performed when the mode switch on the cash register having the same hardware as in FIG. 1 is switched to the program mode.

4 is a flowchart of a method for processing time-based transaction contents according to the present invention, which is performed when the mode switch of FIG. 1 is switched to the registration mode.

Hereinafter, when power is supplied to the hardware as shown in FIG. 1 described in detail with reference to FIGS. 1 to 4, the operation example according to the present invention, the CPU 12 of FIG. 1 scans the key input unit 14 to switch the mode. Search the switch state of. At this time, the mode switch can be switched to a program mode, a settlement mode, a check mode, a registration mode, and a stop mode, which are determined by a user's selection. Here, the program mode is used to set the operation of the cash register. The program mode is used to set and input a unit price for the item key or to program the operation of the cash register. As described above, when the user switches the mode switch to the program mode while the CPU 12 scans the key input unit 14 to retrieve the key input state, the CPU 12 determines that the current mode is the program mode. The routine of FIG. 3 is executed.

The CPU 12, which executes the routine of FIG. 3, scans the key input section 14 to search for the number or item key being input in step 24. FIG. When the user inputs the number of the transaction type for which the user wants to set the unit time and the amount of money by using the numeric keys in this state, the CPU 12 determines that the key is input in step 24 and corresponds to the corresponding key. In step 26, the data is stored in the internal temporary storage memory and returned.

In the above setting, the number of the transaction type is to give a number to the transaction contents. For example, when a billiard transaction is set to "8" and a table tennis transaction is set to "7" at the place where the bill is operated together with the billiard table and the table tennis table, the number becomes the transaction type number.

As described above, the CPU 12 storing the key data of the numeric key or the item key returns to step 24, which is the initial process of FIG. 3, to search whether the numeric key or the item key is input, and when the corresponding key is not input. Search the input status of end key, clock key and start key through 28, 30, 32 search process. When the user who inputs the transaction type number enters the start key while the CPU 12 analyzes the key input in the above 28, 30, and 32 processes, the CPU 12 inputs the start key. Is detected in step 32.

In step 32, the CPU 12, which determines that the start key is input, searches and determines whether the transaction type number is input in step 34 as the stored contents of the internal temporary storage memory. At this time, if the numeric key data is stored in the internal memory, the CPU 12 determines that the transaction type number has been input in step 34 and sets the transaction type number input display flag in step 36. In step 36, the CPU 12 that sets the transaction type number input display flag moves and stores the transaction type number stored in the temporary storage buffer in the internal memory area in step 38. If the transaction type number is not stored in the internal temporary storage area (Buffer), it is determined that the transaction type number is not input in step 34 and an error process is performed. At this time, the error processing unit displays an error message through the display unit 20 or drives a buzzer (not shown) for processing.

As described above, when the transaction unit number and clock key for the transaction contents are inputted using the numeric and clock keys of the key input unit 14 in the state of storing the transaction type number in the internal memory, the CPU 12 described above. In step 24, the input of the numeric key is recognized and stored in the internal temporary storage area in step 26.

When the clock key input from the key input unit 14 is input in step 330, the CPU 12 recognizes the input of the clock key. The transaction unit time is a reference time unit for charging a fee, and represents a unit time of 10 minutes, 20 minutes, 30 minutes, and 1 hour unit. In step 30, the CPU 12, which determines that the clock key is input, reads the contents of the internal temporary storage buffer and searches in step 40 whether the unit time is input. If the unit time is input in step 40, the CPU 12 searches whether the transaction type display flag set in the internal memory is set in step 42. If the transaction type display flag is set in step 42, the CPU 12 transfers and stores the unit time stored in the temporary storage buffer in the internal memory in step 44, sets the unit time input display flag in step 46, and returns it. Wait for the new key to be entered. If the unit time is not input in the above process or if the transaction type number display flag is not set, it is determined that the input is performed in the wrong order and the error processing as described above is performed.

When the user inputs the amount of money per unit time and the end key as the numeric key and the end key of the key input unit 14 while the transaction unit time by the above operation is stored in the internal memory, the CPU 12 in step 24 described above. Recognizes the input of numeric keys and stores them in the internal temporary storage area in step 26. At this time, the amount per unit time by the numeric key is to determine how much to impose on the transaction unit time (for example, 10 minutes) as a reference amount of the transaction unit time. In step 28, the CPU 12 recognizes the input of the end key.

Recognizing the input of the end key in step 28, the CPU 12 reads the contents of the internal temporary storage buffer in step 48 and searches whether the amount of money per unit time has been input. When the amount of money per unit time is stored in the internal temporary storage buffer, the CPU 12 reads the contents of the internal memory in step 50 to determine whether the unit time input display flag is set.

If the unit time input display flag is set in step 50, the CPU 12 stores the unit time stored in the internal memory and the amount of unit time stored in the temporary storage buffer in the internal memory as shown in FIG. Store in In this case, the address stored in the unit time for each transaction item and the reference value storage area B per unit time in the memory map area of FIG. 52 is stored as an address using the transaction type number input in the above process.

For example, if the input transaction type number is "1", the unit time and the amount per unit time are stored in the transaction "1" area of the memory map of FIG. The CPU 12 storing the unit time and the amount of money per unit time input in the above process resets the transaction type input display flag and the unit time input display flag (Reset = Ø) to terminate the setting program.

By using the same method as in FIG. 3, a plurality of transaction contents in units of time can be set, and a unit reference time and amount thereof can be set in a memory as shown in FIG.

The following describes the operation process when the hourly transaction is actually made.

In order to process the transaction contents in the unit of time and issue a receipt thereof, the mode switch in the key input unit 14 of FIG. 1 should be set to the registration mode. If the mode switch is switched to the registration mode as described above, it is recognized by the CPU 12 scanning the key input unit 14 at a predetermined period. At this time, the CPU 12, which has recognized the state of the registration mode, jumps to the routine of FIG. 4 to process the transaction contents in the unit of time and searches whether the numeric key is input in step 56.

In the above state, when any customer comes to the store for the first time and deals with the transaction type, the user starts a transaction by giving a short message indicating the transaction type and the number of distinguishable customers in the customer. . At this time, if the user inputs the customer number written in the wording handed to the customer by using the numeric keys of the key input unit 14, the CPU 12 determines that the numeric key has been input in step 56 and the data corresponding to the input number. Stores and returns to memory.

When the user presses the clock key of the key input unit 14 after inputting the customer number as described above, key data (time data) for the clock key is input to the CPU 12. At this time, the input of the clock key is detected by the CPU 12 by the operation of the CPU 12 searching for the type of the key as shown in FIG.

In step 64, the CPU 12, which determines that the clock key is input, reads and stores the data stored therein as to whether the customer number is input in step 66. If the customer number is not entered as a result of the 66 step search, an error is processed, and if it is determined that the customer number is entered, the CPU 12 sets the customer number input flag in step 68.

The CPU 12 performing step 68 designates and returns a transaction item storage memory area corresponding to the customer number input in step 70 to search for an input of the next key. Designating a transaction item memory area in step 70 designates a corresponding customer area in the storage area of the memory map of FIG. 2 using the input customer number as an address.

After the user inputs the clock key as described above, when the user enters the transaction type number and the start key using the numeric keys installed on the key input unit 14, the CPU 12 uses the numeric keys in step 56 described above. The transaction type number entered is stored internally in step 58 and returned.

Thereafter, when the start key is input, the CPU 12 recognizes the input of the start key in step 62 and searches whether the transaction type number is input in step 72. If a transaction type has been entered, the CPU 12 checks in step 74 whether the customer number input display flag set in the internal memory is set. If the customer number input display flag is not set in step 74, it is determined that the input procedure is wrong, and if it is set, a transaction type number (transaction item) is stored in the customer-specific transaction details storage memory area A in step 76. And CT (local time; Current Time) output from RTC (Real Time Clock) 24 are stored as a transaction start time (ST: Start). In step 78, the CPU 12 resets and returns the customer number input display flag to search for the next key input.

When the processing is completed by the start of one transaction by the above operation, it is possible to store and process the contents of the transaction as allowed in the memory of FIG. 2 by repeating the above procedure.

Accordingly, the transaction processing capacity varies according to the size of the memory of FIG. 2.

If the user registers on the cash register that the hourly transaction for N customers has started by the above operation, and the customer's hourly transaction ends (e.g. when the parked car goes out), press the customer number and the end key. As a result, one transaction is closed, which is operated in the following order.

Even if the transaction of any customer is terminated now, if the user enters the customer number table that was handed to the customer at the beginning of the transaction and indicates the customer number and the end of the transaction with the numeric and end keys on the key input unit 14, the CPU 12 Determines that a numeric key is input in step 56 and stores it in internal memory in step 58.

In step 60, it is determined that the exit key is input, and in step 80, the internal memory is read to determine whether the customer number is entered. If it is determined in step 80 that the customer number is input, the CPU 12 reads the CT (current time) from the RTC 24 in step 82 and stores the current time as an end time (ET). As described above, the CPU 12 storing the current time CT of the RTC 24 as the transaction end time ET calculates the transaction time T by subtracting the transaction start time ST stored in the transaction contents storage area from the transaction end time ET.

The CPU 12 calculating the transaction time T in step 80 checks the transaction item storage area of the customer number input in step 84 and confirms the transaction type. When the transaction type is confirmed by the transaction type confirmation process, the amount per unit time is checked from the memory and the amount of the actual transaction time is calculated using the transaction time and the amount per unit time.

The CPU 12 that calculates the actual transaction amount in step 84 outputs the actual transaction amount calculated in step 86 to the display unit 20 so that the user can know how much the customer should calculate. A receipt is issued by printing the transaction type, transaction time, base price per unit time, and actual transaction amount.

CPU 12 issuing a receipt as described above to clear all the contents of the memory area corresponding to the customer number (Clear) to process all the contents of one transaction.

Therefore, the present invention repeats the above steps and automatically processes the transaction of time unit for all the customers stored in the memory by simple key operation.

As described above, the present invention registers all the transaction contents made by the unit of time for each customer, calculates the transaction contents by the unit of time by simple key operation, and automatically issues a receipt, thereby increasing the use efficiency of the cash register. There is an advantage that can reduce the calculation error by manual calculation.
